elisa reader filter needed ANY HINTS ? / SLT lab instr.

[T. Lenhard]

We have an Elisa reader from SLT, but this company 
does not exist anymore. Was it bought by another company ?
We need a filter for the Elisa reader (450 nm), but do
not know where to start looking ! Any hints are welcome,

Thanks,
